2 stories - one is my mother in law. She smoked for 40+ years and tried halfheartedly to quit, claiming it was her only vice and leave her alone about it. She decided 8 years ago to give it a real try and went to the doctor and he prescribed Chantix. She was able to stop in about a month and hasn't smoked since.

My neighbor, a heavy drinker and smoker, had a mild heart attack at 56 years old and was scared into quiting (smoking - he is Irish and said he'll never quit drinking but switched from beer to 7 & 7s for some reason). He tried using the electronic cigarettes and had no real success. Tried the Chantix and did better, but it is too soon to see if he really quit or not.

Good luck with quitting - it is worth it.
